Combined ovarian tumors are found in common pathologic practice due to amazing potential of ovarian tissue to copy almost every tissue of human body and imitate many neoplasms of various other organs in a very flexible way. A multicystic tumor is presented in this case report of 35-year-old woman. It consisted of a cyst with sebum and hair and cavities with papillomatous projections and mucus. The ovarian tumor was diagnosed a mature cystic teratoma presenting mainly as dermoid cyst and mucinous adenocarcinoma in situ, arising within atypical proliferative mucinous tumor. This report demonstrates how histoformative properties are reflected in ovarian tumorigenesis. Such a stunning histoformativity makes ovaries the possible site of primary origin for malignant tumors that mimic extra ovarian differentiation. In the authors’ point of view, the diagnosis of primary ovarian mucinous tumor within cystic teratoma is firm, whenever simultaneous extraovarian involvement by mucinous neoplasm is excluded.
